WHEEL-RIM.

Specification of Letters Patent.

Patented Feb. 1, 1916.

Application filed. September 22, 1914. Serial No. 862,905.

To all whom it mag concern: Be it known that I, -HENRY J AnnNo, a citizen of the United'States, residlng at Quincy, in the county of Adams and State of Illinois, have invented new and, useful Improvements in Vvhe el-Rims, of which the following is a specification. p

This invention relates to wheels, and per tains more particularly to that type of wheels in which the pneumatic tire is readily. removable therefrom, a section of the wheel being adapted to carry the tire whlch is detachably secured in place thereon by a removable'section of the wheel.

In the accompanying drawings, in which like reference characters indicate similar parts, Figure l is a perspective view of the main section or body portion of my wheel rim; Fig. 2 is a similar view of the-tirecarrying section thereof; Fig. 3 is a detail view showing the means'for locking the flange 2 is provided with a shoulder 4, the

tire-carrying ring to the body portion of .the wheel, and Fig. 4 is a sectional view of my wheel rim taken on the line of Fig. 3. Referring more particularly tothe draw-' ings, the reference numeral 1 designated the main section of thewheel rim which is provided on its outer periphery withan annular flange 2, this flange being provided on oneside of the body portion 3 only. The

purpose of which will be. described hereinafter. On the body portion 3 of the main section 1 are ap'lurality of circumferentially arranged lugs 5, said lugs'being substantially of oblon'g shape, and spaced equi-- distant apart. v i

The tire-carrying member comprises a ring 6 havingan annular-shoulder 7 on one side of its outer periphery, and an annular flange 9 on its inner periphery, the purpose of each of which will be hereinafter set forth. On the inner periphery of the tirecarrying member are a plurality of Iugs15,

- one edge .of which lies flush with the outer edge of the ring as shown. The inner edges of said lugs are provided with recesses 16, and each extremity of the lugs is beveled,

and a. straightportion 17 connects the beveled extremities with the recessed portion. Surrounding the outer periphery and of greater width than-the same, is secured a band 18', adapted to carry the tire-holding rings.

' The main section is provided with a circular opening '20, and the tire-carrying member is also provided-with an opening 21, whlch openings are adapted .to be brought into register when the parts are assembled to permit the projection of the valve stem of the inner tube of the tire.

In assembling the parts, the-tire together with its' casing is positioned on the tire carrying member 6, the valve stem of the inner tube being passed through the aforementioned circular opening 21. After the tire has been positioned on the tire-carrying member 6, the latter is positionedwith the spaces between th lugs 15 opposite the lugs 5 on the outer'periphery of the main section 1,

and the tire-carrying member is then forced.

pver the main section 1. \Vhen the parts are in the posltions described. the circular ring or band 18.1'ests against theshoulder of the main section 1-, this shoulder 4, forming the support for the free edge thereof. After the parts have been thus far assembled, the

tire carrying member is moved circumferentially around the main section 1 until the lugs 5. thereon engage in the recesses of the lugs 15 on the tn'e-carrymgmember held.in place, and is secured therein by the expansive pressure of the tire. when in- 'whereupon the tire carrying member 6 is When i-t is desired to remove the tirecarrying member, it is only necessary to turn the same untilthe lugs 15 thereon reg-- ister with the spaces betweenthe lugs 5 on the main section whereupon ily'removed.

it may be 'read- The construction and operation of my device-will be readily understood from theforegoing description and by reference to the accompanying drawings, and it w ll be appreciated that the parts and combinations thereof may be "varied within the scope of the claim without departing from the spirit of the invention.

Having thus described my invention, What I claim as new'and desire to be secured by Letters Patent, is"

A wheel rim, comprising a main section. a plurality-of radial lugs on the face thereof, a tire-carrying ring adapted to telescope said main section when assembled, means for securing a tire thereon, a plurality of elongated lugson the inner face ofthe ring, the inner edge of each of which is provided with a recess intermediate of its ends and which edge is beveled at one end, the lugs on the main section being adapted to pass between the lugs on the ring in assembling H.
